Description

I have a project that needs to extract a very big maven zip artifact.

I use the maven dependency plugin (unpack goal) with the marker to avoid the extraction at each compilation.

This very big artifact is currently in development, so I use its SNAPSHOT version.

Sometimes a new version of this SNAPSHOT is pushed to Nexus, so when I compile my project (using mvn install), the maven dependency plugin unzips the new SNAPSHOT version but the problem is that the outputDirectory contains a mix between the old version and new version of the artifact.

For example, the first version of the SNAPSHOT contains two files:

Foo1.bin, Foo2.bin

The second version of the SNAPSHOT contains two files:

Foo1.bin, Bar1.bin

The outputDirectory contains:

Foo1.bin, Foo2.bin, Bar1.bin

Whereas I would need to have only Foo1.bin and Bar1.bin.

Because it's a very big file, it's not possible to always compile using "mvn clean install" instead of "mvn install" because extraction takes too much time. I need a way to process the extraction only when the big artifact has been modified.

That is why it would be nice to have an option to clean the outputDirectory before the extraction.

I have a pull request that I can submit if you agree to add this new feature.
